2 Claims. (cl. 158-63) Burner I Conn, a corporation This invention relates to hydrocarbon burners and particularly to that type of such burners having means for vaporizing the fuel by the combustion thereof on said binner.

An object of this invention is to provide a bumer for hydrocarbon fuel which is highly emcient in its operation from the standpoint of fuel consumption, lack of carbonization and attention r quired.

Another object of this invention is to provide a burner which is extremely simple and therefore economical to construct and a further object is to provide such a burner having novel advantages for increasing the efiiciency thereof as well as simplifying its construction.

Further objects and advantages of our invention will be clearly understood from the following description and from the accompanying drawing in which:

Figure 1 is a view in side elevation of our improved burner showing the same installed within a heater partially shown in section.

Figure 2 is a side view showing our improved burner in central vertical section with portions thereof removed therefrom.

Figure 3 is a front end view in elevation.

Figure 4 is a view in vertical section on line 4-4 in Figure 2.

As illustrated in the drawing, the numeral 5 denoteathe bottom portion of a heater of a type which is adapted to receive our improved burner. The numeral 8 denotes the burner proper which consists of a tubular body formed in the shape of a retort comprising an upper vaporizing chamber portion I, having a fuel receiving portion l contained within an upper tube 9. A lower tube portion i0 forms a vapor distributing chamber Ii having oppositely slanting walls It with openings ll therein in which disks H are mounted with jet openings It for the passage of fuel vapors from the said distributing chamber.

Fuel is supplied to said burner through a fuel supply pipe l6 communicating, through a fuel control valve IT, with a nozzle I8 which delivers the said fuel directly into the fuel receiving portion 8 of the vaporizing chamber 1.

In order to provide a positive draft for moving the vapors from the fuel through the said burner and out of the jets, a blower I! of a conventional type is provided. The said blower has a jet pipe l8 extending therethrough and connected to a gas supply pipe for a purpose to be hereinaiter described.

Hartford.

As shown in the drawing, it will be noted that a dam wall ii is provided at the entrance to the vaporizing chamber 1.

Baflle ribs 22 are provided on the walls of the vaporizing and distributing chamber.

An electric pro-heating element 23 is mounted within a tube 24 which extends lengthwise of said burner in the relatively thick wall separating the said vaporizing chamber from the distributing chamber. This heating element may be of any suitable conventional type and removable mounted within the said tube 24.

In order to support the said burner, a flange 2! is provided and supporting foot sections 26 are secured thereto, at the opposite sides of the burnor body, by means of screws 21.

A foot 28 is attached to the burner, near the opposite end thereof by means of a plug extension 28 which fits in the end of the lower-tube portion it and is retained therein by means of a set screw 80.

The said burner may be connected as desired to the heater 5 by means of the flange 3! at the front of the tube forming the vaporizing chamber.

The operation of our improved oil burner is as follows:

When it is desired to ignite the burner, it is first pro-heated by energizing the heating element 1% through an electrical connection therewith, not shown, for a short period of time. After the burner has been pro-heated by said element, the same is deenergized and the valve i1 is opened, permitting fuel to enter the jet pipe i8 and the fuel receiving portion 8 of the chamber I. The blower i9 is started in operation at the same time that the fuel valve i1 is opened. Upon striking the heated surface of the burner, in the fuel receiving portion 8, the said fuel will become vaporized and be forced, by the air current created by the blower, through the said vaporizing chamber '1, into the distributing chamber ii and out through the jets it therefrom into the atmcsphere of the heating chamber in the heater t where the vapors from said fuel are burned at the said Jets it. The said .iets project the products of combustion outwardly, in a relatively diverging direction from the slanting walls I2, to heat the said heater 5 and at the same time heat the tube 9 which is disposed above the said Jets in a position to receive heat from the combustion which takes place at said jets.

It will be noted that the said burner tubes are cast in one piece and cross-sectionally in the shape of a figure 8 having the jets on the lewer burner as e the air' currents, it has been found highly ad portion so that combustion thereon will heat the upper portion. v

In theor the vapors through the being moved therethrough by While we have described and illustrated one embodiment of our invention, it is to be understood that the novel elements. disclosed may be used in other types oi burners without semen: from the scope of the appended claims;

We claim:

"i. A burner comprising a unitary having a horizontally vaporizing chamber, means for supplying fuel to said vaporizing chamber, a vapor chamber underlying said vaporizing chamber and parallel therewith, rows oi air.and inmanycasestheflames wouldbecomef extinguished either from too much iuel or too much air in the mixture.

Furthermore, our improved burner can be installed evenby an unskilled person and still give very satisfactory results since the baiiles have made accurate adjustment of the burner unimv portant.

In cases where the electric pre-heating element is provided, it is not necessary to have the pipe 20 ior connectin a supply of gas to said burner. The said supp y is intended solely ior'use when it is desired to pre-heat the said burner by means of fuel gas instead of by electric energy. when .iuel gas is used for pre-heating the burner, the

supply of gas is turned on through the pipe 20 at the same time that the blower I8 is started. This forces the gas directly through the burner and out through the jets where it is ignited. The combustionthereirom will pro-heat the burner to a point where the said gas may be'shut ed and the supply of hydrocarbon fuel can be started through the valve l1.

iets separated by said body and in opposite sides thereof on a plane below said vaporizing chamber and communicating with said vapor chamber to direct flames from said data for heating said vaporizing chamber along the length thereof; the said body having an elongated opening extending therethrough between the said vaporizing and vapor chambers, a tube in said opening and electric heating means removably disposed within igii tube and projecting iromthe ends or said 2. A fuel burner-oi the character described comprising an elongated body made from a single casting and including a vaporizing chamber I in the upper portion of said body, a vapor chamber underneath said vaporizing chamber and communicating therewith at one end of the said body, the said bodyhaving flat sloping surfaces in the sides thereof and below the said vaporizing chamber and said surfaces having burnertiets therein communicating with the said vaporchamber, electric heating means in said body between said. chambers, means for supplying fuel into said vaporizing chamber, a flange integral with said body and means secured for supporting said body.
